The iPhone 5, iPhone 4S and the 10-inch iPads now sport lower price tags at Walmart, as the retailer started offering new discounts.

The move to cut prices for existing Apple devices is widely seen as preparation for Apple's next-generation iPhones and iPads.

Apple launched its iPhone 5 back in September 2012, followed by the iPad 5 and iPad Mini October the same year. The company is now widely expected to unveil its next-generation iPhone 5S, as well as a much-rumored budget iPhone 5C, at a special event on Sept. 10. Some rumors suggested that Apple might also introduce new iPads at the same event. Judging by the company's previous launch schedules, however, the iPad 5 and iPad Mini 2 will likely make their debut in October.

Ahead of the expected unveilings, Walmart has not cut the price of some iDevices. The 16GB iPhone 5 is now just $98 on a new two-year contract or eligible upgrades on Verizon, Sprint or AT&T. The new discount cuts $30 off the previous $128 price tag for the smartphone.

The iPhone 4S, meanwhile, was previously priced at $89 but is now just $39 on a new two-year contract or eligible upgrade from Verizon, Sprint or AT&T, allowing for more notable savings.

Walmart is also shaving $50 off the price of the 10-inch iPads, offering the 16GB Wi-Fi only version of the iPad 4 with Retina Display for $449 and the iPad 2 for $349. The tablets were previously available for $499 and $399, respectively. The discounts apply to both the black and white color options of the iPads.

The iPad Mini, however, is not included in Walmart's current price cuts. The 16GB Wi-Fi version tablet continues to be available for the same $329 from the retailer.

While Apple has yet to confirm plans for its next-generation iDevices, such discounts from various retailers suggest that new launches are imminent. Apple fans who don't necessarily want the latest devices, meanwhile, can take advantage of such offers and get the iPhone 5, iPhone 5S, iPad 4 or iPad 2 for less than they would normally pay for the devices.
